To 11]] whom, it Duty cancer/t:

Be it known that we, HARVEY Coats and Lewis S. (inmaixsnntonn, citizensof the United States, residing at Baltimore, Maryland. have inventedcertain new and useful improvements in Bottle-FormingImplements, ofwhich the following is a specification.

Our invention relates to the manufacture of bottles adapted to be sealedby metallic caps: and it consists of a special form and construction ofa tool designed to form on the head of the bottle at one operation aninner and outer configuration adapted to receive an inner and outerseal. In this method of sealing bottles generally used to hold liquidsunder pressure the metallic caps and plugs are held firmly in place bybeing bent under a shoulder on or in the neck of the bottle near themouth. These shoulders are formed by making peripheral grooves in theglass, which grooves are made by a tool moved around or held while thebottle is turned and while the glass is in a plastic state.

Heretofore two kinds of seals have been used by us, one in which a metalcup-shaped plug has been inserted in the mouth of the bottle andexpanded against interposed packing into the internal peripheral groove,in which it firmly remains, while with the other form of seal the bottlehas an external shoulder, over which the flange of a cap containingpacking is bent in locking engagement. Heretofore, also, a specialbottle has been provided and used for each seal. lVe have conceived theidea of uniting these seals in one closure for the purpose of atfordinggreater security and especially adapted to be used in bottles liable togreat internal pressure as, for example, when shipped to hot climates"-and this requires a bottle having a peculiarlyshaped head capable ofreceiving the new closure.

To this end we have constructed a bottlemaking instrument, as hereinshown, adapted to form the bottle-head with both an internal andexternal shoulder so related to each other and so located in thebottle-head that our improved integral double closure may be used, orthat form of double closure may be employed in which'an inner seal and aseparate outer cap are used jointly, or either the inner seal or theouter cap may be used alone and yet the strength of the bottle notmaterially impaired.

Our invention is illustrated in the accompanying drawings, in whichFigure 1 shows the instrument in side elevation. Fig. 2 represents acentral longitudinal section in a plane parallel with the sides. Fig. 3shows an edge view of the instrument. Fig. A is a side view representingthe working end or jaws of the instrument and in position to form thebottle. Fig. 5 is a detail view substantially on the line 5 5 lookingfrom the left of Fig. 2. Fig. (i is a sectional view on line 6 6 of Fig.2. Figs. 7 and 8 represent diiferent forms of closures for which thebottle formed by our invention is adapted.

The closures which may be employed on the bottle as a result of ourinvention are indicated in Figs. 7 and 8. In the former ligure theclosure comprises an inner seal a, expanded into the groove and beneaththe interior shoulder, and a crown having its flange pressed intolocking contact with the exterior shoulder on the bottle. In Fig. 8 thebottle as produced by our invention is also provided with interior andexterior grooves, furnishing shoulders into locking engagement withwhich the inner part a of the closure is expanded, while the outerflange formed in one piece with the inner part is pressed into lockingengagement with the exterior shoulder. It will also be obvious that thebottle as provided by our present invention, herein after described, maybe used interchangcably with single closures. such as shown at 11, Fig.7, or with that shown at in the same figure used separately.

Referring now to the apparatus embodying our invention, the drawingsshow two arms land 2 hinged to each other at 3 and provided with aspring 1, tending to keep the arms asunder, but yielding under pressureof the hand grasping the instrument at A. Iln

jointed ends.

and the extensions inclose the spindle.

divided by a slot 7, extending through a part of said spindle from sideto side, and in this slot is a pair of levers 8 8, pivoted on lugs onthe arms 1 and 2. The levers are pivoted in the block'on screws 9 9 andhave ends 10 1O projecting beyond the pivots. The arrangement of theseparts is such that when the arms are compressed the ends 10 10 arethrown out beyond the periphery of the end 11 of the spindle and whenthe arms are open the inner faces of these levers at 10 are in contactand limit the outward movement of the arms. The lever ends 10 10 ontheir outer faces are shaped as shown at 12 and constitute formers forthe shaping of the interior peripheral groove, their withdrawalpermitting entrance of the tapering point into the mouth of the bottleand their projection beyond the periphery of the spindle causing themwhen the tool or bottle is turned to form the groove. They are so shapedas to form a ledge 13 and inclined shoulder 1 1 in the mouth of thebottle all around the interior.

In order to form the outer shoulder in the bottle-head, the inner facesof the jaws 15 of the arms 1 and 2 are provided each with a transversegroove 16. These grooves are bounded by the edges 17 and 18, and eachgroove lies within a larger transverse groove or cavity bounded by theedges 18 18', extending transversely across the inner face of the arm.This larger or main groove serves to provide the enlargement on theexterior of the bottle forming the head. The edge 17 of the supplementalgroove 16 lies approximately opposite the crest of the former 12, andthe edges 17 and 18 of this groove form an outer bead on the bottle-headat the same time that the enlargement is produced, and the formers 12press into the glass to form the groove and shoulder on the interior ofthe bottle-neck at the same time the end of the spindle in the turningof the bottle or instrument finishes the throat of the bottle. A singleapplication of the tool to the material completes the bottle and fits itto receive all the different forms of closures above mentioned.

In order to hold the spindle 5 firmly in central position and preventside play, we have provided special means at or near the hingejoint bywhich a socket will be furnished nicely fitted to the spindle. For thispurpose each of the arms 1 2 near the hinge-pin is provided with a lugor boss 18 having a lateral extension 18 at one side extendingsubstantially at right angles to the main part of the lug and reachingalongside of the spindle Fig. 6, so that the inner faces of the lugsEach lug at or near its lower face is provided with a flange or rib 20to bear on the periphery of the spindle to furnish the means whereby thesocket may be accurately fitted to the spindle. This flange projectsfrom the lug and its extension in a direction substantially at rightangles to the axis of the spindle to bear with its edge against the sideof the spindle. The arms are preferably formed by casting them with thelugs, and any inaccuracies in the fit of the socket to the spindle maybe removed by simply filing away the edge of the flange or rib to securea perfect fit.

As stated above, the crest 17 is substantially opposite the former ends12, and .we mean by this that the said parts are so located as to formthe shoulders in the positions indicated in Figs. 7 and 8 or anyequivalent relation.

We claim 1. An instrument of the class described comprising, incombination, arms carrying jaws, each having a transverse main groove orcavity bounded by the edges 18, 18 within which lies a supplementalcurved groove 16 bounded by the intermediate edge 17 and the said upperedge 18 which bounds the main groove, said structure forming anoverhanging shoulder on the bottle and a terminus to the rounded surfaceof the bottle-lip, formers between the arms having ends 12 arrangedsubstantially opposite the edges 17 of the supplemental grooves, andmeans for operating the formers.

2. In combination, in an instrument of the class described, a pair ofhinged arms, a spindle having its end adapted to enter the bottle mouth,and a socket for the end of the said spindle at or near the hingeconnection comprising the lugs 18 having the flanges 20 to bear on thespindle, said flanges projecting from the lugs in a directionsubstantially at right angles to the axis of the spindle to bear withtheir edges against the side of the spindle substantially as described.

3. In an instrument of the class described, having hinged arms and acentrally-disposed spindle, each arm having near the hinge alug with alateral extension lying substantially at right angles to the main partof the lug and extending alongside of the spindle, said lugs with theirlateral extensions forming a socket receiving the end of the spindle,and each lug with its extension having a flange projecting inwardlytherefrom and bearing against the side of the spindle, substantially asdescribed.

In testimony whereof we aflix our signatures in presence of twowitnesses.
